Abstract (en)

[origin: EP4047549A1] An artificial intelligence (Artificial Intelligence, AI) terminal-based image detection method and apparatus, and an electronic device are provided. The method includes: obtaining a to-be-detected image (S101); determining a light source region of the to-be-detected image and a foreground region of the to-be-detected image (S102); and determining a blurring degree of the to-be-detected image based on the light source region and the foreground region (S103). Impact of a light source on clarity of the to-be-detected image is determined by performing light source region detection and foreground region detection on the to-be-detected image, to effectively detect whether an image shot in a backlight condition is blurred.
